Azure Backup is a service that you can use to back up (or protect) and restore your data in the Microsoft cloud. It replaces your existing on-premises or off-site backup solution with a cloud-based solution that is reliable, secure, and cost-competitive.
Azure Backup offers several components that you might use depending on what you want to backup:
To create a backup policy for Azure VMs, follow these steps:
Consideration | Description |
---|---|
Regulatory Compliance | Ensure that the backup policy meets the legal and regulatory retention requirements your company faces. |
Recovery Point Objective (RPO) | Determine the maximum acceptable amount of data loss measured in time. |
Recovery Time Objective (RTO) | Decide on the target time you set for the recovery of your data. |
Cost Management | Balance the cost of backups with the level of protection, considering the frequency, retention duration, and type of storage. |
Data Criticality | The more critical the data, the more often it should be backed up and the longer it should be retained. |
In summary, creating and configuring a backup policy in Azure involves determining what data to backup, defining the backup frequency and retention policy, attaching the policy to resources, and consistent monitoring of the backup process. Remember, the backup strategy must align with the organization’s RPO, RTO, compliance requirements, and cost considerations. Efficiently managing backup policies ensures that data is available when needed and contributes to the organizational resilience strategy.
Answer: B) False
Explanation: Azure Backup is a cloud-based service that does not require an on-premises service to manage backup and restore operations. It can directly back up Azure VMs, SQL workloads, and on-premises VMs to Azure.
Answer: B) To define the schedule and retention rules for backups
Explanation: A backup policy in Azure Backup is used to define the frequency, schedule, and the retention rules for the backups.
Answer: D) Monthly, weekly, daily or multiple times a day
Explanation: Azure Backup allows backups to be scheduled monthly, weekly, daily, or multiple times a day, depending on the requirements.
Answer: B) False
Explanation: Azure Backup does not currently support backing up Azure Blob storage. It focuses on virtual machines, SQL databases, Azure file shares, and on-premises servers.
Answer: A) Recovery Services vault
Explanation: A Recovery Services vault is an Azure Resource Manager resource used to manage, operate, and monitor Azure Backup services across different Azure regions.
Answer: A) True
Explanation: Azure Backup provides built-in encryption for backups at rest, ensuring that your data is secure.
Answer: B) A temporary deletion that allows for recovery within a grace period
Explanation: Soft delete is a feature that retains backup data for an additional period of time after a delete operation, allowing for recovery if the delete was accidental.
Answer: D) All of the above
Explanation: Enhancing security for backup data can involve using resource locks to prevent unwanted deletions, role-based access control (RBAC) to manage user permissions, and encryption keys to ensure data is encrypted and secure.
Answer: B) False
Explanation: Azure Backup does support the backup of Azure Managed Disks directly or as part of an Azure VM backup.
Answer: B) Geo-redundant storage (GRS)
Explanation: Geo-redundant storage (GRS) replicates your data to a secondary region (hundreds of miles away from the primary location) to provide a higher level of durability in case of a regional outage or disaster. It maintains three copies in the primary region and three in the secondary region.
Answer: A) True
Explanation: Azure Backup policies can be applied across multiple subscriptions provided they are within the same Azure Active Directory tenant.
Answer: D) Premium Block Blob Storage
Explanation: Azure Backup does not currently support backing up Premium Block Blob Storage accounts. It works with Standard General-purpose v1, General-purpose v2, and Blob storage accounts.
Azure Backup is a cloud-based backup solution that helps protect data and applications from human errors, hardware failures, and other disasters.
To set up Azure Backup, you need an Azure subscription, a Recovery Services vault, and a VM that you want to back up.
A backup policy is a collection of settings that define when and how to back up data. It includes settings such as backup frequency, retention period, and backup window.
To create a backup policy in Azure Backup, you can use the Azure portal, Azure PowerShell, or Azure CLI. In the Azure portal, navigate to the Recovery Services vault that you want to configure, and then click on Backup policies to create a new policy.
A backup policy schedule defines the frequency and timing of backups. You can choose to back up data daily, weekly, monthly, or at a custom interval.
A retention range is the period of time for which backup data is retained. You can choose to retain backups for a few days, weeks, months, or even years.
A backup window is the time period during which backups are scheduled to occur. You can choose a specific time window when backup operations will be least disruptive to your workloads.
An application-consistent backup ensures that the data is backed up in a consistent state, which means that the backup captures all in-memory data and metadata at the time of the backup.
A recovery point is a snapshot of the data that has been backed up. You can use recovery points to restore data to a specific point in time.
A Recovery Services vault is an Azure resource that is used to store backup data and manage backup policies. You can create a Recovery Services vault in the Azure portal or through Azure PowerShell or Azure CLI.
